Worked Solution & Example Answer:A wire, which is wrapped around an iron nail, is attached to a battery, as shown in the diagram - Junior Cycle Science - Question d - 2014
Step 1
What happens to the nail when an electric current flows through the wire?
Answer
When an electric current flows through the wire wrapped around the iron nail, the nail becomes magnetic. This occurs because the electric current generates a magnetic field around the wire, which magnetizes the iron nail, allowing it to attract other ferromagnetic materials.
Step 2
How could this effect be demonstrated?
Answer
This effect can be demonstrated by using the magnetized nail to pick up small pieces of iron or steel. Additionally, you can bring a compass near the nail; the nail's magnetic field will affect the compass needle, showing that the nail has become a magnet.
